1.04x0.26
=(1+0.04)x0.26
=1x0.26+0.04x0.26
=0.26+0.04x(0.25+0.01)
=0.26+0.04x0.25+0.04x0.01
=0.26+0.01+ 0.0004
=0.2704
=(1+0.04)x0.26
=1x0.26+0.04x0.26
=0.26+0.04x(0.25+0.01)
=0.26+0.04x0.25+0.04x0.01
=0.26+0.01+ 0.0004

解:
方法一
1.04*0.26
=(1+0.04)*0.26
=0.26+0.0104
=0.2704
方法二:
1.04*0.26
=(100+4)*26/10000
=(2600+104)/10000
=2704/10000
=0.2704
方法三:
1.04*0.26
=(1+0.04)*(0.3-0.04)
=0.3*1-0.04+0.04*0.3-0.04*0.04
=0.2704
方法一
1.04*0.26
=(1+0.04)*0.26
=0.26+0.0104
=0.2704
方法二:
1.04*0.26
=(100+4)*26/10000
=(2600+104)/10000
=2704/10000
=0.2704
方法三:
1.04*0.26
=(1+0.04)*(0.3-0.04)
=0.3*1-0.04+0.04*0.3-0.04*0.04
=0.2704
